PAPER-FEEDINQ MECHANISM.

1 1 I Applicationfiled April 8, 1922. Serial No. 550,801.

To all whom it may concern: e Be it known that I, CLIFTON CHIsHoLM, a

citizen of the United-States, residing at Cleveland. in the county of Cuyahoga and 5 State of Ohio, have invented a certain new and useful Improvement inPaper-Feedin Mechanism, of ,which the follow-ing is a fulf,

clear, andexact description, reference being 7 of the objects of this invention to provide a machine having adjustable means thereon,'so that any desired portion of the paper sheet fed thereto may be brought to position to receive the impression. A further object. of the provide a machine in which the paper may be initially fed by hand, after which it is advanced under control of the operator, to printing position.

An additional object .of the invention is to provide a feeding device for a printing machinehaving a paper support and actuating mechanism for the feeding device, controlled by manual movement of the paper support.

A more specificobject of the invention is to provide a paper feeding .mechanism hav ing a pivoted paper tray thereon and wherein, after the paper has been manually fed to receiving position on the tray, the latter may be depressed to cause the feed rolls to move the paper to printing position. This may be accomplished by providing a paper feeding mechanism embodying a paper tray r or support which is responsive to a depressing movement of the operators arm or hand, the movement of thetray being such as to effect the actuation of lever mechanism arranged to couple the feeding mechanism to driving means after a sheet has been manually fed from a stack of sheets on the support to a receiving position in the feeding mechanism, whereby the paper feeding 4 movements and the power control moveinvention is to ments of the operators hands may be confined to the lmmediate vicinity of the paper stack.

A preferred form of the machine is provided with means whereby the operator moves the top sheet from the stack to position against a movable stop member, the

paper being suitably guided to this'position, and the operator thereafter depresses the paper holding tray,resulting in the throwing 1n of a clutch member which causes the paper feeding rolls'to operate and at the same time removes the stop member, wherebythe paper may be moved by the feed rolls and carried to printing position. The distance from the. end of the sheet at which the prmtlng occurs maybe varied by means of a cam member carried on the drive shaft on whichfthe clutch is mounted. The machine also provides means whereby the op-.

eration of the clutch on moving the tray may be prevented when desired, and means whereby the tray itself may be entirely removed from the machine.

The means for performing theabove and other objects will be apparent in the following description, taken in connection with the accompanyingdrawings, wherein Fig. 1 is a plan View of an embodiment of my invention as applied to the addressing machine described and claimed in my application Serial No. 426,412, filed November 26, 1920; Fig. 2 is a side elevation of the paper feeding mechanism and connecting means for controlling an intermittently operable clutch on the ma chine; Fig. 3 is. an end elevation of paper supporting means and clutch operating means associated therewith; Fig. 4 is a fragmentary end elevation of the paper supporting means showing the clutch operating means in a clutch releasing position; Fig. 5 is a cross sectionalelevation taken'substantially along the line 5-5 of Fig. 1 and showing the relation of-the various elements of the paper feeding mechanism when the paper is being fed thereby; Fig. 6 is a frag-- mentary side elevational section of the paper feeding mechanism showing the members thereof in their normally inactive relation;

Referring to the drawings by reference characters, I have shown at 10 suitable standards or uprights which may be carried on the body of an addressing machine or similar mechanism. These standards, it will be noted, are spaced and are provided with bosses 11 through which a rod 12 passes. Secured to this rod I show a pair of spaced supporting members 14 having enlarged heads 15. A bar 16 secured to the heads 15 by fastening members 17 serve to keep the supporting members aligned.

Pins 18 (Figs. 1, 15 and 16) project forwardly from the supporting members 14 and are arranged to fit apertures in engaging members 19 carried by the paper tray 20. This-tray comprises a bottom portion and a pair of side flanges. The front of the tray is turned down as at 21 and to this 4o turned down part I secure a bracket 32 b means of suitable fastening members 24. X rod 25 passes through holes in arms 26 on the bracket and is held in lace by aset I screw 27. The ends of the rod have arms 28 slidably mounted thereon and adjustably held by set screws 29. The arms 28 have L-shaped paper guides 30 secured thereto, which guides each have one le of the L contacting with the tray 20 an the other an upstanding to guide the paper. The guides may be moved in and outto fit' difl'erent sizes of paper and may be secured in position by the set screws 29.

To enable the depression of the tray to release the clutch, I provide the following mechanism; the bracket 32 on the tray has :1 depending portion 33, and on this depending portion I pivotally mount a latch member 34, which is normally held in contact with a pin 35 by means of a spring 36. The lower end of the latch 34 has a shoulder 38, and adjacent the shoulder is a beveled portion 40. Rods 41 secured to the uprights 10 at 42 are connected at the front of the machine by ineans of a cross member 43 being suitably held by fastening means 44. On

this member 43 I show a pivotall mounted clutch controlling lever 46 which as a head 47 thereon; the latter member normally bearin against the shoulder 38 on the latch 34.

leans for arresting the downward movement of the tray may comprise inverted L- shaped members 41 secured to the bottom 'urged against the pin 35. by the spring 36.

The pin 50 is secured on the cross member 43, and consequently when the tray is depressed, the beveled end of the latch 34 will ride down on this pin, at the same time pressing down the head 47 to rock the lever 46. At a certain period of its'movement, the pin 50 pushes the latch 34 to one side to free the head 47 of the lever so that the lever 46 is free to return to initial position.

Pivoted on one of the standards I show another lever 52 which is connected by means of a link 53 with the lever 46 so that the movement of the paper tray will cause movement of the lever 52. The arrangement is such that the end 55 of this lever will move in the same direction as the paper tray. This end 55 of the lever 52 is provided with a cam surface 56 (Figs. 10 and 12) which acts to throwin and out a clutch 60.

The clutch mechanism shown in Fig. 10 is constructed as follows: The shaft on which the paper feed roll is secured has a pulley 66 loosely 'journalled thereon. This pulley is mounted on a sleeve 67 keyed to the shaft. This sleeve includes a flange portion 68 in which are slidably mounted a pair of pins 69. These pins 69 are arranged to move through apertures in the flange 68. while a portion of each pin 69 is of a reduced diameter, as at 70, and the portion of reduced diameter is fitted into a ring 71 which is mounted to slide on the sleeve 67. A friction element 72 is secured on the ends of the pins 69 and indicated as coned to fit within a coniform recess 73 on the drive pulley 66. The shaft is indicated as mounted in a bearing 74 carried on the standard 10 of the the clutch ring has started, the lever 52 is returned to normal position and a beveled portion 56 thereon now stands in the path of the pin 95 so that as the clutch is completing a single rotation the pin 95 engages and rides outwardly on this beveled port on, moving the ring 71 to the right and opening the clutch.

Keyed to the sleeve 67, I show a cam member 64. At the opposite end of the sleeve 67 from that occupied by the cam, I secure a cup member 75. This cup member is n orn'ially made to rotate with the sleeve, belng secured by means of a bolt 80 to a disc 82 keyed on the shaft 65. It will be noted that rotation of the cup 75 rotates the cam relative to the shaft, and this is effected by loosening the bolt 80 moving in the slots 81. Thus the angular relation of the cam 68 and shaft may be adjusted. When the relation of the cam 64 with respect to a certain portion of the drive wheel 66, or other part of the machine, is desired to be changed, I loosen the bolt 80 and turn the cup 7 5, thereby t-urning the cam 64 to the desired position, whereupon the bolt 80 is tightened and the adjustment is completed.

It is frequently desirable that the operation of depressing the paper tray will not cause the clutch to be thrown in and out, and for controlling such action at will, the following arrangement is provided. The lever 90, .pivoted at 91 to the side frame of the machine, is pivotally connected at 92 to a second lever 93 which has a slot 94 near one'extremity. This slot is adapted to have sliding movement over a screw or projection 95 on the clutch control lever 52. It will be noted that the lever 90 is extended, as at 96, and is provided with a headed portion 97 to allow operation thereof.-

From the. description, it will be apparent that the depression of the headed portion 97 will straighten the levers 90 and 93, thereby moving the control member 55 downwardly and away from contact at all times with the clutch. At the same time through the system of levers 53 and 46, the head 47 of the lever 46 will be lowered from contact with the latch 34. Thus movement of the feed tray up and down would merely cause the latch 34-to be moved back and forth by the pin 50, without in any way affecting the clutch.

The levers 90 and 93 may be brought into or out of alignment through a manual rear ward or forward shifting of the lever 90*, which may act upon the lever 90 by contact with pins 90 and 90 respectively. -The lever 90 may also be utilizedto effect operation of the clutch members and is therefore secured to a plate member 90 which is pivotally secured to a shipper lever 90". plate member 90 also serves to connect the clutch mechanism to stop mechanisms which automatically disengage the clutch from the driving means in the maimer shownand de- The scribed in my applications, Serial No. 419,- 222, filed October 25, 1920 and Serial No. 425,476, filed November 20, 1920. p

The lever 90 may be suitabl mounted on one of the standards 10, where y shifting of the shipper lever will cause pins 90 to slide the ring member71 along the sleeve 67. It will be noted that the operation of the shipper lever may be effected irrespective of the relative positions of the lever member 90 and levers 90 and 93, the pins 90 and 90 being of suflicient length to be engaged by the lever member 90 regardless of the position of the shipper lever 90% When it is desired to drive the machine continuously, for instance when printing envelopes, the lever 90 may be shifted rearwardly, toward the right in Fig. 2, while still in engagement with the flat sprin member 90 which acts to maintain the s 'pper lever in au outward clutch-engaging position.

In Fig. 14 an alternative clutch construction is illustrated which embodies a rearrangement of the immediate clutching elements of the mechanism, whereby a positive coupling of the parts is effected by pm membei's being brought into engagement in suitable slots formed in the hub 66* of the drive wheel 66 as illustrated at 66". The pins 70 are carried by the collar 71' in the same manner as the pins 69, as shown in Fig. 8.

It sometimes happens that it is desirable to remove the tray 20 entirely from the ma chine and use other means to feed envelopes. When this is desired, the tray 20 is withdrawn from the supporting pins 18 and the supporting members 14 are swung about the shaft 12 until the notches 98 in the latch 97,

secured on the supporting member, engage over the pins 91.

The mechanism for feeding the paper to the printing rollers will now be described. The feed roll 100 is indicated as mounted on the shaft 65 and is adapted to be driven when the clutch member 60 engages the pulley 66. Cooperating with this feed roll 100, I show feed rolls 101. These rolls-101 are mounted on a shaft 102, which has its ends secured in levers 103 pivoted at 104 to the supporting member, and are made up of a plurality of rollers each mounted on the same shaft and spaced apart for a purpose to be presently described.

The lever 103, it will be noted, in shape suggests a bell .crank with the portion 105 formed with a tip 106 which is adapted to contact with the under surface of a paper stop 112. The lever 103 is provided with oifset lugs 110 on which a paper guide member 111 is secured. The paper stop 112 referred to comprises a top portion 114 having side flanges 115. pivoted at 115 to the supporting members 14. The top portion also has a turned-down back portion 116 from which a plurality of fingers 117 depend. These fingers are spaced to span the spaced rolls comprising the feed rolls 101,see Fig. 17.

\Vhen the paper stop is in lowered position as shown in Fig. 8. the fingers 117 extend down to a point even with .the bottom of the paper tray 20. One of the levers 103 carries a roller 130 and is normally maintained in position to cause this roller to engage the cam 64 on the sleeve 67 bynieans of a spring 121. while a second spring 125 engages a projection 126 carried on the paper stop 112 to hold the stop normally down.

From the preceding description, it will be seen that rotation of the cam 64 causes the levers 103 to rock about their pivots, with the result that when the roller 130 moves down the levers 103 move the paper stop device 112 up, thus removing the obstruction to the advance of the paper, while at the same time the end 120 of the paper guide 111 is carried down by the projection 110 of the levers 103, and this serves to bring the paper into position to be engaged by the feed roll 100 and the rolls 101, the latter having also moved down with the levers 103.

\Vhen the operator is feeding paper to the machine, and moves the sheet to printing position, there is a tendency for the forward end of the moved sheet to raise above the bottom of the tray. In order that the 1 end of the paper may be held down, I accordingly, provide the positioning member 111 mentioned above. This positioning member extends entirely across the machine and as stated is secured to lugs on the levers 103. The positioning member comprises a forwardly extending portion 118 which is inclined upwardly, whereby the paper will strike it as it has advanced and the forward end of the paper will be guided into position adjacent the feed roll. The other end of the positioning member 111 is bent upwardly as at 120, and it will be apparent that when the levers 103 are rocked, this end 118 will move down and carry the paper with it into contact with the feed roll 100. The forwardly projecting portion 120 of the paper positioning member is indicated as notched to receive the paper feed rolls 101 in the notches.

The operation of the machine is as follows: A stack of sheets are placed upon the tray 20 by the operator and the top sheet is manually fed forwardly into the feeding mechanism with the edge thereof in-cont-act wit-h the depending stop fingers 117, and immediately upon the consummation of this manual feeding of the sheet the operator exerts pressure on the tray while commencing the operation of grasping and feeding the next sheet from the stack. The depressing of the tray causes a swinging movement thereof about its axial mounting on the rod member 12, thus bringing about actuation of the clutch controlling levers at? and 52 in the manner hereinbefore de scribed. The end 55 of the lever 52 is thus shifted out of engagement with the clutch members, as indicated by the dot and dash position in Fig. 12, and the shipper lever 90 is shifted outwardly from the machine under the influence of the spring member 90 upon the lever member 90. The clutch member 72 is thus brought into engagement with the clutching surfaces 73 of the fly wheel hub and rotation is imparted from the fly wheel to the shaft 65.

The manual feeding of the sheet with the top edge thereof into contact -with the fingers 117, and between the rearwardly extending portion 120 of the guide member 118 and the rest )late 122, positions the upper portion of t e sheet between the feed rolls 100 and 101, as indicated in Fig. 7.

As the shaft and cam 64 rotate, the levers 103 are drawn forwardly under influence of the spring 121, when the depression in the cam permits movement of the cam follower 130, as indicated in Figs. 5 and 13. This forward movement of. the levers 103 carries the feed rolls 101 downwardly into engagement with the paper sheet. The guide portions 120, disposed between the rolls 101 likewise are carried downwardly into contact with the sheet, and serve to prevent a crimping or wrinkling of the paper, thus maintaining the paper in comparatively smooth engagement with the roll 100 as it is moved thereby.

The stop fingers 117 will have been raised by the action of the camming portion 110 of the levers 103 prior to the final downward engaging movement of the feed rolls 101 onto the upper surface of the sheet. The sheet thus has a free movement. The paper sheet is guided by suitable means, not shown, in a downward direction until engaged by the platen roll 160, illustrated in Fig. 13. Near the completion of one revolution of the shaft 65 the cam 64 will have again acted upon the cam roller 130. thus effecting the repositioning of the various members of the sheet receiving mechanism whereupon another sheet may be positioned between the feed rollers by the operator.

In the meantime, the pin 95 will have revolved into engagement with the cam surface 56 on the end of the lever 52 and the clutch disc 72 will be disengaged from the driving wheel 66 and shifted to the position indicated in Fig. 10. The shifting of the pin 95 likewise effects an inward movement of the shipper lever 90", resulting in a, comprewing of the clutch member 90 by the lever member 90.

If it is desired to increase the space between the top edge of the sheet and the first line of the printed matter, the angular relation of theram and the pin 95 will be changed (see Fig. 12), whereby the amount of angular movement of the feed roller 100 before feeding engagement of the roller member 101 with the sheet will be increased. On the other hand, if it is desired to decrease t-he space the amount of angular movement of the feed roll 100 before engaging the sheet will be decreased. As the pin 95 is fixed relative to the shaft 65, the desired increase or decrease in the space between the printed matter and the topmargin of the sheet may be brought about by turning the hand wheel 75 to the left or to the right respectively. To effect this adjustment, the bolt 80 is loosened and the shaft is maintained stationary while the sleeve and'cam are adjusted. The amount of this angular adjustment is limited only by the angular span of the rise on the cam.

It will be noted fro-m the foregoing description, that the advantages which will be found in my invention include the quick detachability of the entire feeding mechanism, involving only the simple movement of replacing the feed mechanism in relation to the feed roll 100 by swinging the paper tray and the feed mechanism including the lever 103 about its pivotal axis on the rod 12 upwardly until the hook members 97 can be locked on the pins 91. If desired, the paper tray 20 may then be removed from the machine by sliding the tray out of engagement with the pin members 18, whereupon an envelope magazine may be positioned on the machine by engagement thereof with the pins 18 when in this elevated osition, as described in my application, erial No. 424,114, filed Nov. 15, 1920.

Furthermore, the clutching mechanism, as hereinbefore stated, may be positioned for continuous operation by bringing the lever 90 into proper relation with the spring member 90 whereby the clutch will be maintained in continuous engagement with the driving wheel, and the clutchlever 52 will be maintained out of engagement with the clutch by the same operation through alignment of the lever members 90 and 93. It will be noted, furthermore, that the arrangement of the various elements in the feed mechanism is such that the depressing movement of the tray by theoperator does not in any manner affect the efficient functioning thereof when the sheet is being acted upon by the feed rolls 101 and 100.

The feeding and clutching mechanisms are associated in such a manner that the movements of the operator in feeding the sheets into the machine, are confined to the immediate vicinity of the stack of sheets positioned on the tray, whence the attention of the operator may be primarilyidirected to the constant removal of the sheets singly from the stack and the continuous position-' ing thereof within the feed mechanism, while attention to the intermittent driving of the machine is but a secondary matter in the efficient operation thereof, due to the fact that the operation of the clutching 7 feeding rolls, a clutch to operate said paperfeeding rolls, means to support a stack of paper, and means whereby movement of the paper stack supporting -means causes said clutch to operate said paper feeding rolls.
